loud noise coming from middle to end of car

[AnthonyMuscatt]

hi all i have a 04 hilux and when i am driving at speeds of about 50km/h + i hear a humming noise coming from the middle to rear of the car, the sound can be heard when i am accelerating, maintaining speed and also when i am decelerating, i was wondering if anyone else has had this problem and what they did to fix it and what my problem is i’m guessing it’s the rear diff but i am not 100% sure cheers

Check the Universal's before opening the diff'
